However, I am not sure how well these details would work when applied to $30,000 houses.As for the things you always hear about - AC units, furnaces, coils and water heaters.  

There is a spring like coil tool you can buy if it becomes a repetitive issue.3) If they request the floor strip to be fixed, then just knock it out on your visit.

Hey JordanReduce your cost dramatically your in Texas so your mostly non-union hire some guys to do the tear off you can get that done for around 600 bucks buy 16 squares of asphalt shingling  have it delivered, hire a guy with an air compressor and nailer offer him 35 bucks a square he'll be done in less than 3 hrs.

I have put about 6 roofs on with a masterforce roofing nailer with not a single problem.

So I would probably have someone take a look at the units to be sure they are charged properly, filters are clean, coils are not dust-covered, etc. 

You could also install hardwood, but that requires a special flooring nailer - which could be rented - and an air compressor.In the bathroom, you could remove linoleum or outdated tile and replace with tile.

However I suspect there is a rattle snack coiled up under that tempting welcome mat. 

The best way to explain a heat pump is, a central air conditioner that has something called a reversing valve that diverts the refrigerant so during the winter months the inside coil is hot and the outside coil is cold.

If you know someone, you could get a new 2.5 ton unit, line set, a-coil, new disconnect box (if needed) installed for around $2000-$2500.

I really want to keep them out of the 203k loan because I don't think we're getting good pricing from the contractor.  1 - 2.5 ton Goodman R410 14 SEER Heat Pump System2 - 80% 80k BTU Natural Gas Furnace Coils (I assume the A/C condensers are included here too)He wants over $15k ($9k parts $6k labor) to replace the three outside units and the furnace coils.
